Abstract: 1456051 Feeding sheets SITAV SpA SOC INCREMENTO TURISTICO ALBERGHIERO VALDOSTANO 4 Sept 1974 [28 Sept 1973] 38677/74 Heading B8R Playing cards are separated simultaneously from two piles 40 and 41 by friction means (e.g. rollers 38 and 39) and delivered to an outlet slot 17. The piles are contained on edge in a removable magazine 42 and are urged towards the end wall 44 of the magazine by a weight 48 which rides on rollers 52. Backward movement of the weight is prevented by a tongue 53 thereon which engages a rack 54 on the magazine floor. The rollers 38 and 39 may be replaced by friction fingers and the weight by resilient means. Actuation of the rollers is by means of a pivotted lever 28 which turns a gear 27 (via pawl 33) and the gear rotates pinion 35 and 36 provided on the roller shafts. The magazine may be withdrawn through the rear aperture of cavity 4.

Abstract: 921,759. Automatic control systems for aircraft. UNITED AIRCRAFT CORPORATION. Oct. 30, 1961, No. 38795/61. Class 38 (4). [Also in Group XL (c)] A safety arrangement for an automatic control system comprises a circuit which passes only signals below a predetermined magnitude. It comprises a pair of diodes 22, 24 connectedanode to anode, to which the input from transformer 10 is applied via resistor 18 and potentiometer 20, the output being obtained from transformer 34. The diodes are normally biased conductive by means of a positive bias applied to the anodes over resistor 30. The signal from transformer 10 is also applied via resistor 38 to rectifier 40, the output of which is smoothed by capacitor 42 and applied via resistor 44 as a negative bias to the anodes of diodes 22, 24 ; an excessive signal input causes these diodes to be biased non-conductive, so that no output reaches the transformer 34.

Abstract: 1435837 Boots, &c DESMA - WERKE GmbH 16 Aug 1973 [23 Aug 1972] 38810/73 Heading A3B [Also in Division B5] The invention relates to a method of making multi-layer soles from material of low viscocity comprising the steps of injection moulding an outer sole layer 13 and then injecting an inner sole layer 12 so as to become connected with the outer layer, the inner layer 12 also becoming connected to a shoe upper 10 either by being moulded integrally with the upper or by being moulded onto a lasted upper. According to the invention, during injection of the outer sole layer 13 the mould comprises a removable counter plunger 18 (Fig. 1) instead of the last 15 (Fig. 3). The material for the outer layer may be injected into an enlarged mould cavity 23 and is then compressed against the counter plunger by raising a bottom plunger 17. After the outer layer material has partly set this process is repeated for the inner sole layer, using the last 15 in place of the plunger 18. In order to ensure that the outer sole layer is held on the bottom plunger when the counter plunger is removed, the bottom plunger may be provided at several points with depressions (29) Figs. 5, 6 (not shown) into which the injected material is forced. In Figs. 7 to 9 (not shown) the upper is moulded as well as the inner sole layer by raising the bottom plunger (17a). In Fig. 10 (not shown) two lasts (35, 36) and a counter plunger (37) are mounted on a head (34) which is rotatable about an oblique axis. In Fig. 11 the bottom plunger 17b is fixed and the counter plunger 18b is provided with an extension 38 fitting into a recess 21b which is used to form an extended welt part (14b) on the inner sole layer (12b) Fig. 12 (not shown). The inlet passages 22b and 24b for the moulding material may be shut off by an element 40. For Figures see next column

During positive half-cycles of the input, diode 12 is cut-off and amplified half-cycles appear at 17. On negative half-cycles, total negative feedback over the now conducting diode 12 prevents any output at 17. In other embodiments, Figs. 7 and 8 (not shown), resistor 19 is partly decoupled by a capacitor or by using diodes to provide some of the bias. In a further embodiment, transistor 11 is directly fed at its emitter and capacitor 14 is connected between base and earth, Fig. 6 (not shown). A.G.C. may be provided by using the output at 17 to supply a voltage divider 38, 39, Fig. 9, which biases mixer transistor 32 while simultaneously using an anti-phase output from the emitter to vary the impedance of transistor 40 in parallel with resistor 39.

Patent GB-400804-A (GB)
Abstract: 400,804. Thermal switches. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A. -(Assignees of Allgemeine Elektricitats- Ges.; 2, Friedrich Karl-Ufer, Berlin.) Jan. 11, 1933, No. 976. Convention date, Jan. 11, 1932. [Class 38 (v).] A thermal relay with time delay comprises a bimetallic strip 1 having its end 10 bent upwards in close proximity to a ratchet wheel 2 controlled by a spring 11 and carrying a contact 12. When the lines 7, 8 are energized, for instance by an overload relay, a heating coil 6 causes the strip 1 to move upwards and engage the wheel 2 to rotate it. The circuit of the heating coil 6 is however interrupted at 4, 5 and the strip returns. At the same time a pawl 3 consisting of a bimetallic strip having a small time lag is heated so as to bend towards the wheel 2 and retain it in its displaced position. Thus as long as the lines 7, 8 are energized the ratchet wheel 2 is advanced step-bystep due to the strip 1 and holding pawl 3. After a sufficient time the contact 12 engages contact 14 and completes a circuit in lines 15, 16. Also contacts 17, 18 are separated to break the circuit of the pawl 3 and the wheel 2 returns to its original position due to the spring 11. If however the lines 7, 8 are de-energized before the contacts 12, 14 engage, the pawl 3 moves outwards on cooling and the wheel 2 returns without performing a switching operation. In use the lines 7, 8 may be energized by an overload relay to complete the opening circuit 15, 16 of a circuit breaker if the overload continues for a sufficient time. Although long time delays are possible, owing to the adding of a number of small time lags in the element 1, the relay is ready for use again quickly after operation as the element 1 cools quickly. In a modification the pawl 3 is connected directly across the lines 7, 8 and the contacts 17, 18 are connected in series with the heating coil 6. This modification is for completing the anode circuit of a hot cathode rectifier a certain time after completing the filament circuit.

In the arrangement for grain drying shown, a 12 position shift register receives a signal from a moisture meter 13 which alternately samples the moisture of the supplied and the dried grain. The meter 13 signal also is added to the dried grain signal at 14 and an average value passed to the summing device 15 where it is added to a desired signal go. As the register steps in synchronism with the grain drier sample moisture readings from steps 3 and 9 are summed and subtracted from the output of summing device 15. The resultant output is applied to control relay 19 which stops the advance for a period which varies linearly with the resultant signal. At the end of the period the discharge mechanism operates for a fixed duration and the moisture of the dried sample is compared with the desired value in subtractor 20 to provide a signal to control relay 19 which alters the standstill time by 1/12th of the amount that would be needed if a single drying operation occurred. Temperature compensation 21 may be provided by temperature sensitive resitors 21 positioned in the drying airflow.
